Who are we ?

One-layer armour technologies using the TETRAPODE, ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™ and X-bloc ® types are works that we describe as "sensitive". Sensitive does not mean fragile. It depends on the care taken in the construction. The armours made using TETRAPODE, ACCROPODE ™, ACCROPODE ™ II, ECOPODE ™, CORELOC ™ and X-bloc ® blocks will be strong and durable if carefully constructed. They will be fragile and will require regular monitoring and repair work to avoid significant damage or simply begin to destroy themselves even before the end of construction as you will see on this site, if they are built without the necessary care.

With over 30 years of experience in maritime inspections and more than 20 years dedicated to construction work, judicial expertise, arbitrations on construction sites, consultants, builders, and international experts involved in the largest global projects, generally full-time , CLAS experts have established a classification of the constructions using TETRAPODE, ACCROPODE, ACCROPODE II, ECOPODE, CORELOC and X-bloc ® according to the care taken in their construction.

With approximately one million blocks installed, expertised or repaired, spread over more than thirty projects worldwide, CLAS is currently the only specialized company that accompanies you on a full-time basis on your projects. CLAS provides inspections, advice, training of personnel and professional divers, analyzes and adapts the HSE and QAQC procedures, analyzes and adapts the construction and implementation procedures on all projects using TETRAPODE, ACCROPODE, ACCROPODEII, ECOPODE , CORELOC and X-bloc ® to bring you safety, quality and high production.
